这是Twitter Bootstrap宝石的错误吗？我还在学习如何得到这个固定的？任何帮助都很棒

解决方法

叽叽witter witter的引导宝石取决于宝石越少.从 the docs：

gem "therubyracer"
gem "less-rails" #Sprockets (what Rails 3.1 uses for its asset pipeline) supports LESS
gem "twitter-bootstrap-rails"

我亲自发现twitter引导程序更容易将文件从official site转储到vendor / assets目录中.从宝石更新比手工更容易,但更新bootstrap时,您有意做“手工”,并且通过眼睛检查全部 – 我更喜欢额外的努力,以确保它不会做得很轻此外,很难从宝石中删除某些(例如)响应部分,而没有(据我所知)“未指定”样式.响应的内容从版本到版本都有变化,所以你不能只依靠它一切工作.我真的看不到使用宝石的任何优势.

更新

现在有一个官方的宝石,我建议退房：https://github.com/twbs/bootstrap-sass
